I recently got a problem. I have no way to change the brightness of my display. I have looked online and tried all the methods I have seen including reinstalling my chipset driver which includes the graphics card. I have tried the power options which has no slider and no other way to change it, the windows mobility center which also has no options for changing it, there is no option in my BIOS related to the brightness settings, and I cannot change it from the Intel Graphics settings utility. I do not know what happened and how it started. Before I was able to change it with no problems and then sometime in November or December I found I was unable to change them. But I don't know if there was an update at that time that disabled that function. And unfortunately I did not look at the updates when the problem occurred. Has anyone else experienced this problem and knows of another solution? I am using Win7 Pro. Oh and the brightness setting is set to the highest basically. The problem is that I cannot change it down not the other way around.
